The important part for most players is that Windsong is now is a useful enchant for all classes and specs, since it will trigger on all damage or healing, be it spell, melee, or ranged, and direct or periodic. Elemental Force will also trigger from all damage, so is useful for all damage dealers.

Additionally, these two enchants use a new system for triggering, which we wanted to give some details on. These are the gritty details, which you do not need to understand in order to use these enchants, but we wanted to detail for the benefit of the theorycrafting community. If mathy simulations and modeling aren’t your thing, none of this will matter much to you.

We have had various methods for triggering procs throughout WoW’s history. Most procs fall into two categories for the past few years:

Relatively high but static proc chance, with a significant cooldown. Most trinkets and caster procs fall into this category. For example, a trinket may have a 30% chance to proc on hit, with a 55sec cooldown. This lets us balance the trinket with a pretty safe assumption of procing about once per minute. Unfortunately, since it’s so reliable, it doesn’t really feel like a random proc, but rather like an On Use trinket that’s just on auto-cast. The uptime won’t increase significantly with any stats with this type of proc.

Relatively low proc chance with some normalization based on weapon speed, typically referred to as ‘PPM’ (procs per minute). Most melee weapon enchants fall into this category. For example, a weapon enchant may have 3 PPM. That checks your weapon speed, and gives your attacks a % chance based on that. If you have a 3.6speed weapon, your attacks will have a 3(PPM) * 3.6(weaponspeed) / 60 (sec per min) = 18% chance. All your white and yellow attacks with that weapon will have an 18% chance to trigger the enchant. Despite being supposedly ‘3 PPM’, that really will result in significantly more than 3 procs per minute, since all of the special attacks can proc it. Since there is no cooldown involved here, this type of enchant can feel random and streaky, instead of reliable. That isn’t necessarily a bad thing though, as you are just as likely to get lucky and get several procs in a row, which can be exciting. Some stats, primarily haste, will increase the frequency of these procs. However, since they vary heavily based on weapon speed, and how many special attacks you’re doing, these can procing significantly more or less for one class/spec/weapon than another, making them difficult to balance.

So, there are pros and cons of both of those types of procs. We’re trying a new system for these enchants. This new system, nicknamed Real PPM, aims to give the random nature of procs, the scaling with haste, and the ability for us to balance them assuming a standard proc frequency. Here’s the short version of how you can expect them to function:

Windsong is 2 Real PPM. Elemental Force is 10 Real PPM.

Regardless of how you’re attacking or healing, slow or fast, with DoTs or direct heals, whatever, you can expect to get the same proc frequency, on average.

Dual wielding and having both weapons enchanted with the same enchant will double the frequency of procs that you get.

This Real PPM is increased by your haste %. (The highest of your melee, ranged, or spell haste is chosen).

Simple as that. Whether you’re an Affliction Warlock dealing very frequent DoT ticks and Malefic Grasp ticks, or a Holy Paladin casting purely Holy Lights, or a Combat Rogue quickly attacking and using specials, or an Enhancement Shaman attacking with slow melee attacks and spells, or a Shadow Priest channeling Mind Sear on fifty Onyxian Whelps, you’ll get 2*Haste Windsong procs or 10*Haste Elemental Force procs per enchant per minute.

We’re excited to see how this proc system works out. If it works well, we may start using it for more types of procs. Feedback about how it feels is most welcome.

Here are even more nitty gritty details, if you’re interested:

It can proc from any damage/healing event. It keeps track of the last time it had a chance to proc for that enchant.

It calculates the difference in time since the last chance to proc. It uses that time to determine the chance for that event to trigger a proc.

For example, if you have 22% Haste, it was 1.4sec since the last chance to proc, and you’ve got Windsong, then the chance to proc is 2(ppm) * 1.22(haste) * 1.4(time since last chance) / 60 (sec per min) = 5.693%.

The ‘time since the last chance to proc’ is capped at 10sec, so that your first attack of a fight isn’t a guaranteed proc.

If you have any questions about this, please feel free to post them here, and we’ll try to answer them.

Is this going to increase the difference in DPS between 2h and dual wielding for monk WW? That'd kinda suck =/ For now I'm dual wielding but want to move to 2h. Double enchants was already one of the main reasons dual wielding was ahead for us...

I have no idea what's going on. Can anyone translate this to casualish?

Rather than having hard cooldowns on procs that make it impossible to get multiple procs in a row, or static proc chances per attack that benefit fast classes more, proc chances will now maintain the random nature of rate-per-attack type procs, but dynamically scale based on the average time Blizzard feels should pass between procs.

Basically, the longer it has been since the last time you hit or healed something, the more likely the NEXT hit or heal will trigger the proc.

Example: Blizzard decided that Elemental Force should proc an average of 10 times in a minute. In other words, once every 6 seconds. Let's say a rogue hits something and doesn't proc, then hits again exactly one second later. That second hit has a 1/6 (16.7%) chance to proc. A mage with the same enchantment casts a spell and fails to proc, then casts it again 3 seconds later (counting cast time). The second cast has a 3/6 (50%) chance to proc. So, on average, both players will see the same number of procs over time.

Elemental Force has 10 Real PPM? Let me calculate that for a 5 seconde interval of procs with 22% haste:
10(ppm) * 1,22(haste) * 5(time since last chance) / 60 (sec per min) = 101,67%
You proc all the time, how is this system better?
